Basically asura gears with a diffrent weapon, also depends on some MVPs. Gonna list some cheap gears that aren't MVP/SQI gears.
For MVPs in memoable places:
Ulle's Cap with Incubus Card.
Midgear with Incubus Card.
An Abysmal Weapon, usually a Quad Abysmal Mace.
Any shield with an Alice.
Morpheus's Shawl.
Variant Shoes/Sleipnirs. Sohee Shoes can do alright too.
2x Mantis Ring, 2x Diabolus Ring, 2x Morpheus's Ring/Bracelet.
Just set up a bragi and dancer in town, and asura/warp. Usually cheaper to just use the doctor NPC to full heal for SP since it takes more than 10 GJ to get full SP and GJ are usually 170-180 ea.
For armor, you can use orlean's robe for no interuption when Asuraing, but it will slow down your casting by a bit.
Now, for MVPs where you can't just memo and asura, that's something diffrent.

The few things you'd want to upgrade from the gears I posted are the accessories to berz, and headgear to kaho. Variant Shoes and Incubus mid actually give around the same, if not, more SP than DL+DI combo. Of course it will be harder to solo with these gears. Be carefull!
